Pointing the camera up a tree doesn't strike me as interesting or requiring much imagination, as evidenced by the number of people who chose to do it for this challenge. At least shooting at a different time of day that offered a more interesting quality of light might have helped. Sorry, 2.
Nice POV - right next to the trunk... but I can't help but think it could be more interesting in Black and white.. just not sure - maybe some cool clouds and other colors would be helpful in the sky also.
Punchy sky, creative title, nice balance of trunk, branches, sky. Minor nit - Brighter foreground stops my eye from being pulled in as easily as it could. In total, well done.
